How to sample 16 X 24 points on rectangle images

Hi, I have tride to set the point_grids parameter to better sample rectangle images but it doesn't seem to work. It porcess but I end up with no masks. Anyone has tried to sample rectangle images?

The issue only mentions the point_grids parameter, rectangle images, and a run that produces no masks; it identifies no file, test, or example. Start by reproducing the result with the image dimensions, parameter value, and model details recorded. Done means determining whether the behavior is a bug or a usage issue and documenting a verified resolution.
